Abstract: A knitting machine includes a needle bed having a groove formed therein, a needle housed in the groove and reciprocatingly slidable therein, a needle cam, a needle cam follower mounted on the needle and engageable with the needle cam, a needle stitch selector and a needle cam disengager responsive to the stitch selector for controllably disengaging the needle cam follower from the needle cam. The stitch selector includes an electromagnetic selection station and at least one selector member which is slidably mounted on the needle bed. The selector member is responsive to the selection station and positioned thereby in one of at least two distinct positions in respect to the needle bed. The needle cam disengager includes a two-arm lever which is pivotally mounted on the bed. The first arm of the lever cooperates with the selector member and its second arm is in communication with the needle cam follower via the needle and acts operatively thereon to disengage the needle cam follower from the needle cam.

Abstract: The device includes a canal having a narrowing entry and a widening outlet, separated by the poles of a pair of opposing electromagnets, and in which selective means, or selectors, are shifted. Two substantially identical, geometrically and magnetically symmetrical selector stations are provided. The entry and the outlet of the canal include a magnetic adherance system, functioning alternately as a stabilizer and as an amplifier of movement, following the direction of the device shifting in relation to the selectors to be selected.
